| 摘 要： | 由于缺陷的大小和分布具有较大的随机性，迄今还没有有效考虑各种缺陷的方法。本文建立了具有考虑初始弯曲几何缺陷的IMEP单元模F型。该单元是以满足约束条件及根据最小势能原理来构造的。计算结果表明：由IMEP单元导出的挠度和刚度系数具有较高的精度。

| Abstract: | Today,effective methods have not been found to consider all kinds of imperfections because of the randomicity of the magnitude and distributing of imperfection.An imperfect MEP element model described explicitly is formulated by using the imposition of compatibility and the principle of minimum potential energy.It is shown that the accuracy of deflection and stiffness coefficient is considerably high. |
